Starbucks ​had no idea how popular their eggnog lattes were — until they took them away.

The coffeehouse giant ​apologized ​Thursday ​for nixing its popular seasonal​ drink and promised to bring it back after the plan made fans of the fatty holiday drink foaming mad.

The coffee chain opted to scrap the flavor last month and replace it with a new praline chestnut latte — sparking freakouts from soccer-mom types and other coffee bu​​ffs in New York and ​across the country, except the Pacific Northwest, where it remained on menus.

Steaming customers took to Twitter to blast Starbucks, saying the firm had stomped on their holiday spirit.

“The eggnog latte was the only thing keeping me from beating people during the holidays. Please bring it back,” one customer blasted on Twitter.
